AIG and McGill & Partners have entered into a long‑term partnership that will deploy 25 % of AIG’s capacity across up to $1.6 billion of McGill & Partners’ gross premiums written in the specialty subscription market. The collaboration is designed to give subscription‑based businesses seamless access to high‑quality insurance solutions backed by AIG’s long‑term capital and capacity.
The deal hinges on agentic artificial‑intelligence and Palantir’s Foundry platform. AIG will use the platform to ingest McGill & Partners’ data, build an ontology of the broker’s portfolio, and enable AI systems to reason about exposures, limits, and risk outcomes in near real‑time. This technology will allow AIG to deploy capacity with greater insight, discipline and speed, and to manage follow‑underwriting decisions more efficiently than traditional manual processes.
Peter Zaffino, AIG’s Chairman and CEO, said, "The rapid evolution of AI and large language models is reshaping risk analytics, giving us the ability to continuously learn from McGill & Partners' portfolio and deploy capacity with greater insight, discipline and speed." Steve McGill, CEO of McGill & Partners, added, "This collaboration has the potential to disrupt the dynamics of the subscription market. It strengthens the value proposition of leading underwriters in the market and redefines the way capacity is positioned in the best interests of our clients. This moves beyond incremental change, and repositions the way the market operates in the future."
The subscription market traditionally relies on a lead underwriter setting terms and follow underwriters deciding whether to participate, a process that can be slow and labor‑intensive. By leveraging AI and a digital‑first platform, the partnership aims to accelerate that decision cycle and provide clients with faster, more transparent access to insurance. AIG’s prior AI initiative—its partnership with Amwins and Blackstone to launch Lloyd’s Syndicate 2479—demonstrates the company’s experience in deploying Palantir technology for underwriting and risk analytics.
Strategically, the collaboration positions AIG to capture a growing share of the subscription‑market segment, a space that is expanding as commercial risks become more complex and insurers seek scalable, data‑driven solutions. For McGill & Partners, the partnership validates its digital platform and expands its reach into a global insurer’s distribution network. Together, the two firms aim to set a new standard for how capacity is positioned and managed in the subscription market, potentially reshaping competitive dynamics and creating a more efficient, AI‑enabled underwriting ecosystem.
